Poor customer service

I have never had a bad experience with Takealot until now, I always supported them and would promote them but that all ends now. I ordered items on the 12th of March, and they went out for delivery on the 26th of March I tried contacting them to let them know that the office is closed but could not get hold of them. My parcel has been rescheduled for delivery, but the address is my work address, which because of the lock down my office won't be opening again. Takealots response to me wanting to change my delivery address is that the parcel must be cancelled. The prices of the items have also conviently increased since I ordered them in March. So if I must cancel my order is Takealot going to pay in the price difference? The items weren't purchased on special but with the increased price its now a so called 11% off. Apparently the system does not allow for a change of a address once the parcel is at a branch, but they can inform the branch if the order is cancelled?? I am sure I am not the only takealot user needs to change a delivery address. If other courier services can do it why can't takealot? I didn't expect such poor customer service from takealot.
